In which of the following compounds B–F bond length is shortest ?
A
B
BF 3 ← NH 3
C
BF 3
D
BF 3 ← N(CH 3 ) 3
Text Solution
Verified by ExpertsThe correct answer is:
C
Partial double bond character is developed in B–F bond of BF 3 (due to formation of dative π bond)
In other case B is sp 3 hybridised (tetrahedral molecule or ion) and the possibility for π bonding no longer exists.
